Abstract:
A disposable camera constructed to produce a single photograph and to collapse to a stored position. A top wall and bottom wall are spaced apart by a pair of inwardly folding side walls and a pair of outwardly folding side walls. A negative is slidably mounted adjacent the back wall and is alignable with a photographic paper slidably mounted against one side wall and to the top wall. A shutter is moveable across an aperture in the front wall to allow light to pass to the negative. A pair of rollers are mounted to the camera box with the photographic paper and negative moving therebetween developing the photograph on the paper.
Abstract:
An agitated and pressurized paint pot that is mounted directly to a paint spray dispenser uses a small volume pressurized pot with constant agitation. This design prevents the settling of material and ensures that the materials are applied through the system at a consistent feed rate to meet the specific needs of applying radar absorbing materials.
Abstract:
A disposable camera having an erectable bellows. A plastic bellows includes a series of truncated, conical walls, interspaced between a second set of truncated, conical walls, all of which form equal included angles with the camera longitudinal axis. The bellows has a proximal end integrally connected to a camera box having a self-developing film packet therein. A pair of rollers apply pressure to exiting exposed film spreading development medium thereacross. A lens and shutter mechanism are affixed to the distal end of the bellows.
Abstract:
A method is provided for forming an extrusion die of the type used to form a ceramic monolith having thin walls defining a multiplicity of parallel tubular passageways with at least about 100 passageways per square inch, the die having a feed face and a discharge face, the feed face having a plurality of feed holes extending partially through said die and interconnecting with a network of grid slots in the discharge portion of said die formed by a plurality of grid pins which define the slot width and the wall thickness, shape and size of said passageways. The method involves the steps of forming the width of the slots larger than the desired wall thickness of the passageways, and metal plating the slot defining surfaces of the grid pins to obtain the slot width corresponding to the desired wall thickness. Plating is accomplished by the electroless plating technique using a metal selected from the group consisting of nickel, chromium, cobalt and cobalt-nickel. The resulting die has a substantially uniform coating of wear resistant metal which is strippable for replating and continued die use.
Abstract:
Machines having a boom or arm pivotally disposed thereon wherein the length of the boom or arm and the angle thereof with respect to a reference plane are adjustable by means of actuators are well known. However, it is extremely difficult, if not impossible, to simultaneously control the actuators in a coordinated fashion to move the end of the boom or arm in a straight line path. In order to overcome this problem, a boom control system for a boom according to the present invention controls the actuators in either of two modes of operation, the first mode of operation comprising independent control over each actuator to afford polar coordinate operation and the second mode of operation comprising synchronized control over the actuators so that the end of the member may be moved in a straight line. Means are provided for manually selecting one of the two modes of operation. Means may be provided for calculating the amount of remaining horizontal throw of the boom or arm when a command to move same is issued.
Abstract:
A disposable camera constructed to produce a single photograph and to collapse to a stored position. A top wall and bottom wall are spaced apart by a pair of inwardly folding side walls and a pair of outwardly folding side walls. A negative and associated photographic paper is slidably mounted in the camera. An externally located pair of pressure jaws receive the film and paper to break a packet of development material mounted to the paper and negative and subsequently apply the material onto the paper. The camera is disposable after one exposure whereas the jaws are retained for use with the next camera. A shutter is moveable across an aperture in the front wall to allow light to pass to the negative.
Abstract:
In accordance with a preferred embodiment, a monolith extrusion die is formed by separately drilling matching feed holes for extruded material in each of two plates. In one plate the feed holes are shallow and carefully drilled for accurate alignment with the extrusion slots of the die. In the other plate, the holes are accurately located at the drill entry point, but thereafter rapidly drilled without regard to drift. The plates are then bonded together to form my die.Other methods of forming an extrusion die using two plates are disclosed.
Abstract:
A method for controlling the coating with alumina of ceramic monolithic catalyst supports on a production basis to achieve repeatability of coating utilizing a vacuum system to distribute a coating slurry of alumina over the interior surfaces of and purge the excess coating slurry from the support at the same time that plugged tubular passageways through the support are unplugged, comprising the steps of applying the coating slurry to the support which has at least about 100 axially aligned tubular passageways to the square inch and subjecting the support to a vacuum to draw the slurry through the passageways and remove plugging and excess slurry to form a coating of alumina on the passageway surfaces. The support is dried and calcined to fix the alumina coating on the passageway surfaces.
Abstract:
A method of operating an air conditioning system includes changing output of the compressor based on a temperature limit of the evaporator. The temperature limit is one of a predetermined fixed temperature limit and a variable temperature limit. The method also includes determining the variable temperature limit by determining a target air outlet temperature for conditioned air in a control space, detecting an actual evaporator temperature, calculating a difference between the target air outlet temperature and the actual evaporator temperature, finding a predetermined first temperature adjustment that correlates to the difference, finding a predetermined second temperature adjustment that correlates to another condition, and calculating the variable temperature limit by adjusting the fixed temperature limit by one of the first and second temperature adjustments.
Abstract:
An improved speaker in which a single electro-acoustic driver is mounted in a sound emitter cabinet with a spheroidal rear acoustic emitter wall, with the driver face exposed and mounted on a driver-mounting face of the cabinet and the driver body enclosed in the spheroid cabinet. The spheroidal rear emitter wall is spaced from and surrounds the driver body to receive the back wave and to responsively emit audible, clear sound from the cabinet wall to the surrounding listening area in complement to the primary sound wave from the driver face. The speaker cabinet is rigidly supported via the driver-mounting face such that the spheroidal rear emitter wall is suspended in air out of contact with surrounding surfaces.
